HYDRAULIC-POWER GENERATOR.

Specification of Letters Patent.

Patented Oct. 31, 19%.

Application filed July 13, 1904. Serial No. 216,393.

To all whom it may concern,-

Be it known that I, ALBION P. WIGHT, a citizen of the United States, and a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and Improved Hyd raulic-Power Generator, of which the following is a full, clear, and exact description;

The object of the invention is to provide a new and improved hydraulic-power generator which is simple and durable in construction and arranged to utilize steam under pressure for expanding water and using the expanded water under pressure as a motive agent for driving a hydraulic motor for actuating machinery of various-kinds.

The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims A practical embodiment of the invention is represented in the accompanying drawing, forming a part of this specification, in which the figure is a sectional side elevation of the improvement, parts being in elevation.

Within a suitably arranged casing A is formed or secured a steam-chamber B, connected by a pipe B, having a valve B with a steam-boiler or other suitable source of steam-supply. The steam-chamber B is surrounded by a water-suction chamber O, connected at its bottom by a suction-pipe D, having a valve D,with a well E, containing water.

The chambers B and O are provided with alined nozzles B O, of which the nozzle O discharges into an expanding chamber F, likewise arranged within the casing A. From the chamber F leads a delivery-tube F into an outlet G, connected by a pipe H with a reservoir I for receiving the heated and expanded water under pressure. On the inner end of the pipe H is arranged a check-valve J for preventing a return flow of the water from the reservoir I into the pipe H.

The top of the reservoir I is connected by a pipe K with a water-motor L of any approved construction, and the discharge-pipe L of this motor L leads to the well E, so that the water is returned to the latter or discharged as waste, if desired.

In the pipe K is arranged a manually-controlled valve N and a valve 0, controlled by a suitable governor P, driven from the motor L, to regulate the amount of water passing from the reservoir I to the motor L, according to the latters load. The reservoir I is provided with a suitable gage I for indicating the pressure.

On the top of the reservoir I is arranged a relief-valve Q, having a pipe Q connected with the interior of the reservoir I, and the said relief-valve Q, is provided with two connected valves Q and Q of which the valve Q is somewhat less in area than the valve Q and the valve Q is exposed to pressure from the reservoir I, while the valve Q, is under pressure of steam passing into the valve Q by a steam-pipe Q, having a valve Q From the relief-valveQ, leads an overflow-pipe Q, to the well E or waste-pipe. Normally the valves Q and Q are closed; but on an excess of pressure within the reservoir I the valves Q and Q open, so that water from the reservoir I can pass by way of the relief-valve Q and overflow-pipe Q back into the well E. Normally the valves Q Q are closed by the pressure of steam from the boiler, the valve Q having the larger area.

In the bottom of the outlet G of the casing A is arranged an air-escape valve R, opened at the beginning of the operation to allow the air Within the casing A to escape, it being understood that as soon as the air has escaped the valve R is closed.

The operation is as follows: When steam is admitted into the steam-chamber B, then water is drawn up from the well E by way of the pipe D on account of the steam creating a suction in the chamber C, the steam and the water passing through the nozzle G into the ex panding-chamber F, in which the water is expanded and driven with great velocity through the delivery-tube F, outlet G, and pipe H into the reservoir 1. IV hen the expanded water in the reservoir I attains a suflicient pressure, then the valve I is opened to allow the water under pressure to flow into the motor L and actuate the same. The water discharged by the motor L is returned to the well E, or to any convenient place, or used over and over again without perceptible loss.

The water used is ordinary water containing air and other gases, and the force obtained is attributed to the expansion by the heat of the air, gases, &c., contained in the water. This expands or increases the volume of the water, provided the water is not heated up to 212 Fahrenheit.

The device may be used in connection with any form of water-wheel or motor for driving steam-carriages, steamboats, or furnishing power in anyway it may be required, and where steam-engines are now used. It is, however, expressly understood that the main feature of my invention is drawing water from any suitable source into a generator or other suitable device for the purpose of expanding it with a jet of steam to obtain a hydraulic pressure that is to form a motive agent consisting of expanded water under pressure.

The steam is employed to draw up the water from the Well and to impart a velocity thereto in the pipe H of about 85.5 miles per hour. the steam-pipe B having about one hundred pounds pressure. No steam passes into the reservoir; but the steam condenses between nozzle C and pipe H, and at about one hundred pounds steampressure a pressure of about one hundred and twenty-live pounds is obtained in the reservoir I. When the steam is at about one hundred pounds pressure, the water in the reservoir 1 reaches about 13 Fahrenheit. while at about two hundred pounds steam pressure the water reaches about 150 Fahrenheit. At the relief-valve Q the steam-pressure-say about one hundred pounds-(being the same as the pressure in pipe B) is overcome only when the pressure in the reservoir 1 reaches about one hundred and twenty-five pounds, this being due to the difference of areas of the valves Q and Q In other words, the relief-valve opens at one hundred and twenty-five pounds pressure in the reservoir I to allow the water to pass back into the well. In operation, a regular working pressure of about one hundred and twen tyfive pounds is maintained in the reservoir 1.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent 1. A hydraulic-power generator,comprising a reservoir, means for drawing water from a suitable source, and for forcing the water into the reservoir, a connection from the reservoir to a motor to be driven under the propulsive velocity imparted to the water, and relief devices connecting with the reservoir and having connections with the water source and a steam source.
